IKO TAF 182620,TAF 192716 Nots
Notes(1) Minimum allowable value of chamfer dimension r
(2) Allowable rotational speed applies to oil lubrication. For grease lubrication, a maximum of 60% of this value is allowable.
Remarks1. TAF series with a roller set bore diameter Fw of 26 mm or less have no oil hole. In others, the outer ring has an oil groove and an
oil hole.
2. No grease is prepacked. Perform proper lubrication.
